Abstract
The fast recovery behavior in negative bias temperature instability (NBTI) in SiON gate p-type metal–oxide–silicon field effect transistors was investigated. The fast recovery is due to the hole detrapping from the K-center (N3Si, where denotes a dangling bond). The Gaussian function-like hole trap energy level distribution explains the universality in the fast recovery. The results shed light on the NBTI mechanism.
